20170340404 · 2017-11-30 ·

A forceps includes a pair of shafts each having a jaw member disposed at a distal end thereof. One (or both) of the shafts is moveable relative to the other about a pivot pin between a spaced-apart position and an approximated position to move the jaw members between an open position and a closed position. A knife assembly includes a knife blade mechanically keyed to the pivot pin and moveable between an initial position, wherein the knife blade is disposed within one of the jaw members, and an extended position, wherein the knife blade extends between the jaw members. An actuator arm(s) is mechanically keyed to the pivot pin and extends therefrom. The actuator arm(s) is moveable between an un-actuated position and an actuated position to rotate the pivot pin relative to the jaw members to move the knife blade between the initial position and the extended position.
